Reddit reviews Before the Storm (World of Warcraft)

You can see A LOT more than the teaser and the epilogue at amazon.

It's not a coup against Sylvanas. The Desolate Council wanted to be NEUTRAL.

Amazon says May 15, 2018.

The short story Edge of Night goes over Sylvanas's suicide after the Lich King was defeated and how she came to enlist the aid of the Val'kyr.

The novel War Crimes by Christie Golden. Focuses on Garrosh's trial in Pandaria, it bridges the gap between Mists of Pandaria and Warlords of Draenor. Sylvanas isn't the main character but she has a few chapters dedicated to her and her relationship with her sister Vereesa Windrunner.

The short story Dark Mirror which explains how Nathanos Blightcaller got a new, not rotting off the bone, body.

There's a new novel coming out called Before the Storm (also by Christie Golden) that bridges the gap between Legion and Battle for Azeroth. It explains what lead up to the burning of Teldrassil and the siege of the Undercity by Alliance forces. Sylvanas is one of the main characters.

>She'd never wanted this. Not really. as she had told the troll Vol'jin before, during the trial of the late and greatly unlamented Garrosh Hellscream, she liked her power, her control, on the subtle side. But with quite literally his dying breath, Vol'jin, the Horde's leader, had commanded that she do the opposite. He had been granted a vision by the loa he honored.

>You must step out of da shadows and lead.

>You must be warchief.

>Vol'jin had been someone she respected, although they clashed on occasion. He lacked the abrasiveness that so often characterized orc-leadership. And she had been genuinely sorry he had fallen - and not just because of the responsibility he had placed on her head.

Alleria has not confronted Sylvanas, yet. That meetup is heavily hinted in 'Before the Storm' novel, the prelude to Battle for Azeroth (similar to 'Tides of War' preluding Mists of Pandaria and 'War Crimes' preluding Warlords of Draenor). There are two noteworthy conversations I'll point out:

On the Vindicaar when Vareesa is basically filling in Alliera on what happened: https://www.youtube.com/watch?v=DVc2OK2L_KA

The other one, is when Alliera and Turalyon return to Stormwind and reminisce about their statues: https://www.youtube.com/watch?v=1k7V8jTGZE0

Editors divergent note/opinion: One thing I'll add which I think is a slight fumble on Blizzard's side is that the latter conversation is something you need to kinda hunt for as an Alliance player, and when Alleria returns to Silvermoon, it is covered in a Horde only scenario (which weirdly covers Nightborne recruiting). There was a clear story thread that feels a bit jumbled since you see this on the Horde side and it doesn't mean that much to them, while you never see this on the Alliance side and there is a clear buildup for that scenario for them but it is far more 'hidden' than the first conversation I linked. My solution to mitigate the fumble would have been at least in the Void Elf scenario to deliver a lot more expostion and Alleria's afterthoughts and Blizzard nudges to get you to play Horde and experience that Nightborne recruitment/Silvermoon scenario.

An easy (and free) way would be the short stories on the official website.

If you're willing to spend some money, Before the Storm will lead right into the next expansion, so you can buy that when it comes out and let them read that.

Also, the backstory for the invasion of Lordaeron is a novel releasing next year:

The book that (hopefully) contains that answer is scheduled to release in june. You can read a sample here.
